Abstract

Przedmiotem zgłoszenia jest sposób scalania piasków, a zwłaszcza piasków rzecznych, kopanych i płukanych, który polega na kontaktowaniu piasku w ilości 80 - 85% wagowych z 42 - 45% wodnym roztworem krzemianu sodu w ilości 7 - 15% wag. w stosunku do scalanej mieszaniny i jego utwardzaczem w ilości 1 - 14% wag. w stosunku ilości krzemianu sodu, nanokrzemionką w ilości 2 - 4% wag. w stosunku do scalanej mieszaniny uprzednio zawieszoną w szkle wodnym, po czym następuje wytrząsanie w formie oraz utwardzanie w podwyższonej temperaturze.The subject of the application is a method of merging sands, especially river, dug and washed sands, which involves contacting sand in the amount of 80 - 85% by weight with 42 - 45% aqueous solution of sodium silicate in the amount of 7 - 15% by weight. 1 - 14% by weight relative to the mixture and its hardener. based on the amount of sodium silicate, nanosilica in the amount of 2-4 wt. relative to the merged mixture previously suspended in water glass, followed by shaking in the mold and curing at elevated temperature.
